Reprojection issue

Hi VCityTeam,

I wanted to get 3Dtiles for Cesium from a gml set of buildings.
Following the tuto "CityGML to 3DTiles pipeline", I imported in a gml file with buildings of the area of Rennes in a 3DCitydatabase.

The header of the gml file give this information:
<gml:Envelope srsName="urn:ogc:def:crs,crs:EPSG::3948,crs:EPSG::5720" srsDimension="3">

Thus, I created a db with the 3DCitydb shell script with this inputs:

_Please enter a valid SRID (e.g., EPSG code of the CRS to be used).
(SRID must be an integer greater than zero): 3948

Please enter the EPSG code of the height system (use 0 if unknown or '3948' is already 3D).
(default HEIGHT_EPSG=0): 5720

Please enter the corresponding gml:srsName to be used in GML exports.
(default GMLSRSNAME=urn:ogc:def:crs,crs:EPSG::3948,crs:EPSG::5720):_

Then, with the py3dtilers script I ran this command:

citygml-tiler -i C:\Users\A\3Dtiles_rennes\CityTilerDBConfigReference.yml --type building --with_texture -crs_in EPSG:3948 --crs_out EPSG:4978

I got all the tiles without issues, I uploaded the zipfile in Cesium.
But I ended up with tiles located in the middle of the north atlantic instead of the city of Rennes.

Is there anything that I missed ? The crs codes seem to be good.

Thanks in advance for your help !
